Topic: [SOLD] Over 1.1 TH/s of Mining Hardware - has to go - page 2. (Read 2012 times)

400x U2 ? 

ID love to see some pictures of that (not because I dont believe you, I just wanna see it).

Thanks for the advice ... I wasn't sure if anyone would be interested but I'm happy to provide proof with a note containing specific text if requested & more than happy to use escrow (although I'm not sure who here provides it)

Thanks

You will need to provide pictures of your actual equipment with username and date on a piece of paper, generic photo's don't mean you actually have anything listed.

Also you forgot to mention if you will use an escrow service. Sorry if I sound harsh but you're a low activity 'newbie' and if I don't ask you to provide this others will . Far too many attempted scams on here lately.

If you would like to get started in coin mining & prefer to get in & get your 'hands dirty' rather than mining in the cloud ... This is the package for you
Well over 1 TH/s of SHA-256 Mining & 32 MH/s of Scrypt plus a Radeon HD 5970 so you can experiment with some of the new GPU algorythms

http://www.sticky-web.net/bct/spacer.png The Scrypt Miner is a GawMiners Falcon (Same as a Zeusminer Thunder) 27MH/s + (Doesn't seem to drop below 32) Super easy configuration Amazing cooling and long quietness Hash Rate: 27MH+ Case Material: Aluminum Chip: 55nm GAW Miners dedicated ASIC Scrypt (QFN Design) Power Consumption: 900W Controller is a Raspberry Pi running CGminer PSU is a EVGA SuperNOVA 1300 G2 which usually powers one of the Eyeboot USB hubs as well		http://www.sticky-web.net/bct/Falcon.png http://www.sticky-web.net/bct/EVGA.png
There are 3 x Antminer S1 clocked at 393 & happily mining 24/7 at 200 GH/s +/- 5% Hash rate: 180 GH/s (Overclock to 200+) Power consumption: about 360 W from the wall Power supply: 3 +12V DC input Power efficiency:  2 W/GH/s on wall Size:  135 mm x 155 mm x 300 mm Network connection: Ethernet Cable / WIFI Cooling: 12cm PWM fans and customized heat sink These mine stand-alone - can be configured via web-interface or SSH & never stop! Each has an additional fan attached at the rear, one has been modified to have the Heatsinks on the outside & has 4 additional fans to draw heat away efficiently & there are enough chip heatsinks to cover all three (not all attached) PSU are an IKONIK Gaia 500 IP-G500A-CBAA 500W, another Generic 500W Supply & I've been experimenting with 2 x 12V Regulated Switching Power Supplies to run the third with good results. (Probably more efficient to run the others this way) http://www.sticky-web.net/bct/spacer.png		http://www.sticky-web.net/bct/S_1.png
There are approximately 400 x Bitmain U2+ USB Miner's that will happily produce 2.2 - 2.4 GH/s each Default hash rate: 2.0 GH/s, over clock by command Power consumption: 2.95 W on USB 5V @ 2 G Power supply: 5 V DC input Size: 60 mm x 25 mm x 15 mm 7 x Eyeboot 49 Port USB hubs + 1 49 Port Block Erupter (needs fuse holder replaced) Controlled by 4 x Banana Pi's running bfgminer that can handle 2 of the Eyeboots each Power is currently a mix of S150 5V 40A Switching Power Supplies & standard ATX supplies Included are at least another 5 of the S150 that need fuses replaced or similar repair and extra ATX - Open End looms. And I'll throw in 4 of the original Antminer U1 & a Block Erupter (if I can find them!) http://www.sticky-web.net/bct/spacer.png		http://www.sticky-web.net/bct/U2a.png http://www.sticky-web.net/bct/Eyeboot49.png
The Radeon HD 5970 Black Edition isn't the latest GPU but it still has sufficient punch to try mining X11/X13/NeoScrypt or other new algorithms with scripts such Sgminer v5 PCI Express 2.0 x16 ATI Radeon HD 5970 Core Clock 725 MHz Boost Clock 1000 MHz Interfaces 2 x DVI-I (dual link) Mini DisplayPort API Supported DirectCompute 5.0, DirectX 11, OpenCL, OpenGL 3.2 Memory Size 2 GB GDDR5 SDRAM http://www.sticky-web.net/bct/spacer.png		http://www.sticky-web.net/bct/HD5970.png

So why the sale?

To be honest, I don't have the time to chase the highest returning pool nor the ability to 'nuture' the miners to keep them all running at their best - all of the controllers could benefit from an upgrade in mining software version & I'm sure that the U2's could be run more efficiently via a larger PSU powering multiple hubs.

With more efficient cooling (I have the heatsinks & fans but haven't had a chance to fit them) the S1's & U2's could definitely be overclocked - there are even threads on bitcointalk.org that discuss replacing components to make the miners more efficient - this kind of fiddly circuit work is beyond me.

There's even been an upgrade kit released for the S1 that boosts performance & efficiency to 453 GH/s while consuming only 355 Watt - again, it's a task that I don't have the time or skills to pursue!


Included are all cables (ethernet, power & usb)
NOT Included are Network Switch & Power boards

Shipping

As you can imagine - all of this swag combined is heavy ...
I'd imagine around 30kg plus heavy.
So Australia Post is probably not going to be an option!

I have plenty of packing materials so they could be shipped as multiple boxes with a Courier (of your choice)
OR
Pick-up from Wendouree VIC 3355.
I can everything packed ready to go - or you can see it operating before dismantling.

Warranty

Used electrical equipment has no warranty (although I will Test & Tag the power supplies if you wish)

There are approx. 50 unopened (therefore NEW) U2+ so you may be able to chase DOA replacement via Bitmain

Overclocking voids Bitmain's warranty & almost everyone wants to attempt overclocking so you may be battling to receive a replacement if you cook your chip whilst attempting to push the limits.

This Screen Grab shows 3 x S1, 5 x Eyeboot & Zeus operating - Other Eyeboots are operational but I'm replacing PSU
